DRSS communication considerations for manned space flight
A lower and an upper bound or manned space flight requirements for a data relay satellite system (DRSS) in the 1975-1980 time period are described. In all cases, the most stringent requirement is an intersatellite link to provide wideband information transfer from an overseas DRS to the Continental United States. A parametric communication analysis is made as a function of varying frequency and antenna aperture. The desirability of using a VHF frequency band for low data rates and voice relay and the requirement for frequencies of 8 and 16 GHz for video and wideband digital data relay are shown
Supporting State Policymakers' Implementation of Federal Health Reform
Outlines the capacities states will need to implement federal healthcare reform in the areas of information and analysis, strategic implementation and planning, topic-specific technical assistance, communications, and coordination and integration
The nature of the long time decay at a second order transition point
We show that at a second order phase transition, of \phi^4 like system, a
necessary condition for streched exponential decay of the time structure factor
is obeyed. Using the ideas presented in this proof a crude estimate of the
decay of the structure factor is obtained and shown to yield stretched
exponential decay under very reasonable conditions.Comment: 7 page
School reform, school size, and student achievement
An estimation of the effect of school size on student achievement, with the results suggesting that market-based school reform could enhance student performance if the reform reduced school size.Education
